mistfly statusline
==================

_mistfly statusline_ is a simple, fast and informative `statusline` for Vim.

:point_right: Neovim users should use the pure-Lua
[linefly](https://github.com/bluz71/nvim-linefly) plugin instead of _mistfly_.

_mistfly_ provides a number of useful builtin components:

- Git changes
- Diagnostic status
- Macro-recording status
- Current search count
- Spell status
- Indent status (tabs or spaces and their associated width)

_mistfly_ also provides optional `tabline` support when the appropriate setting
is enabled; refer to
[`mistflyTabLine`](https://github.com/bluz71/vim-mistfly-statusline#mistflytabline).

_mistfly_ will adapt it's colors to the colorscheme currently in effect. Colors
can also be
[customized](https://github.com/bluz71/vim-mistfly-statusline#highlight-groups-and-colors)
if desired.

Lastly, _mistfly_ is a lean `statusline` plugin clocking in at about 500 lines
of code. For comparison, the
[lightline](https://github.com/itchyny/lightline.vim),
[airline](https://github.com/vim-airline/vim-airline) and
[lualine](https://github.com/nvim-lualine/lualine.nvim) `statusline` plugins
contain over 3,600, 7,300 and 8,200 lines of code respectively. In fairness, the
latter plugins are more featureful, configurable and visually pleasing.

:warning: _mistfly_ has a predominantly fixed layout, this will **not** be an
appropriate `statusline` plugin if layout flexibility is desired.

[Iosevka](https://github.com/be5invis/Iosevka) font with Git changes,
diagnostics and indent-status enabled.

Statusline Startup Comparison
-----------------------------

A startup comparison of _mistfly_ against various popular `statusline`
plugins, with their out-of-the-box defaults, on a clean and minimal Vim setup
with the [moonfly](https://github.com/bluz71/vim-moonfly-colors) colorscheme.
The Vim startup times in the following table are provived by the
[dstein64/vim-startuptime](https://github.com/dstein64/vim-startuptime) plugin.

Startup times are the average of five consecutive runs. Note, `stock` is run
without any `statusline` plugin.

| stock | mistfly | lightline | airline | lualine
|--------|---------|-----------|---------|--------
| 18.0ms | 18.7ms | 22.0ms | 76.0ms | 23.2ms

Startup times as of March 2024 on my system; performance on other systems
will vary.

Plugins, Linters and Diagnostics supported
------------------------------------------

- [vim-devicons](https://github.com/ryanoasis/vim-devicons) and
[nvim-web-devicons](https://github.com/kyazdani42/nvim-web-devicons)

- [Gitsigns](https://github.com/lewis6991/gitsigns.nvim)

- [GitGutter](https://github.com/airblade/vim-gitgutter)

- [Signify](https://github.com/mhinz/vim-signify)

- [ALE](https://github.com/dense-analysis/ale)

- [Coc](https://github.com/neoclide/coc.nvim)

- [Obsession](https://github.com/tpope/vim-obsession)

:zap: Requirements
------------------

_mistfly_ requires Vim 8 (or later), Neovim is not supported. The pure-Lua
[linefly](https://github.com/bluz71/nvim-linefly) plugin should instead be used
with Neovim.

Please also make sure that the `laststatus` option is set to either: `1`, `2`
or `3`.

Installation
------------

Install **bluz71/vim-mistfly-statusline** with your preferred plugin manager.

[vim-plug](https://github.com/junegunn/vim-plug):

```vim
Plug 'bluz71/vim-mistfly-statusline'
```

[lazy.nvim](https://github.com/folke/lazy.nvim):

```lua
{ 'bluz71/vim-mistfly-statusline' },
```

Please do **not** lazy-load _mistfly_.

Layout And Default Colors
-------------------------

The *mistfly-statusline* layout consists of three groupings, the left-side,
middle and right-side as follows:

```
+-------------------------------------------------+
| A | B | C | D M W | X | Y | Z |
+-------------------------------------------------+
```

| Section | Purpose
|---------|------------------
| A`*` | Mode status (normal, insert, visual, command and replace modes)
| B | Filename (refer below for details)
| C`*` | Git branch name (if applicable)
| D`*` | Plugins notification (git, diagnostic and session status)
| W | Optional search count and spell status
| X | Current position
| Y`*` | Total lines and current location as percentage
| Z | Optional indent status (spaces and tabs shift width)

Sections marked with a `*` are linked to a highlight group and are colored,
refer to the next section for details.

Sections C, D & W will **not** be displayed when the `statusline` width is less
than 80 columns.

Note, filenames will be displayed as follows:

- Pathless filenames only for files in the current working directory

- Relative paths in preference to absolute paths for files not in the current
working directory

- `~`-style home directory paths in preference to absolute paths

- Possibly shortened, for example `foo/bar/bazz/hello.txt` will be displayed as
`f/b/b/hello.txt` when `statusline` width is less than 120 columns.

- Possibly trimmed. A maximum of four path components will be displayed for a
filename; if a filename is more deeply nested then only the four most
significant components, including the filename, will be displayed with an
ellipsis prefix symbol used to indicate path trimming.

Highlight Groups And Colors
---------------------------

Sections marked with `*` in the previous section are linked to the following
custom highlight groups with their associated fallbacks if the current
colorscheme does not support _mistfly_.

| Segment | Custom Highlight Group | Synthesized Highlight Fallback
|--------------------------|------------------------|-------------------------------
| Normal Mode | `MistflyNormal` | `Directory`
| Insert Mode | `MistflyInsert` | `String`
| Visual Mode | `MistflyVisual` | `Statement`
| Command Mode | `MistflyCommand` | `WarningMsg`
| Replace Mode | `MistflyReplace` | `Error`

Note, the following colorschemes support _mistfly_, either within the
colorscheme (moonfly & nightfly) or within this plugin (all others):

- [moonfly](https://github.com/bluz71/vim-moonfly-colors)

- [nightfly](https://github.com/bluz71/vim-nightfly-guicolors)

- [dracula](https://github.com/dracula/vim)

- [edge](https://github.com/sainnhe/edge)

- [embark](https://github.com/embark-theme/vim)

- [everforest](https://github.com/sainnhe/everforest)

- [gruvbox](https://github.com/gruvbox-community/gruvbox)

- [gruvbox-material](https://github.com/sainnhe/gruvbox-material)

- [retrobox](https://github.com/vim/colorschemes)

- [sonokai](https://github.com/sainnhe/sonokai)

Lastly, if the fallback colors do not suit then it is very easy to override with
your own highlights.

:gift: Here is a simple example of customized _mistfly_ colors. Save the
following at the end of your initialization file after setting your
`colorscheme`.

```vim
highlight! link MistflyNormal DiffChange
highlight! link MistflyInsert WildMenu
highlight! link MistflyVisual IncSearch
highlight! link MistflyCommand WildMenu
highlight! link MistflyReplace ErrorMsg
```

the numbered window-spaces:

```vim
nnoremap 1 1gt
nnoremap 2 2gt
nnoremap 3 3gt
nnoremap 4 4gt
nnoremap 5 5gt
nnoremap 6 6gt
nnoremap 7 7gt
